From World Oil:"While key global benchmarks Brent and WTI were trading on the futures market in the $20s on 27 March, West Texas Light at Midland sold for $9.40/bbl on the physical market. And Canadian heavy crude oil sold for less than $6/bbl. IHS Markit projects Brent prices to fall to around $10/bbl in April. Some producers may experience “negative prices” where they pay a buyer to take their crude oil."
